Android的MediaPlayer的 - 下载和流媒体在同一时间重新审视 [英] Android MediaPlayer - Downloading and Streaming at same time revisited

问题描述

这个问题已经被问过，但现在随着Android的新版本（最多果冻豆），我想知道是否有一直在下载和在同一时间的流文件的任何进展。从API，它看起来并不像它的本质可能的，因为这些都是可用的setDataSource方法：

This question has been asked before, but now with the newer versions of Android (up to Jelly Bean), I was wondering if there's been any progress on downloading AND streaming a file at the same time. From the API, it doesn't look like it's inherently possible, as these are the available setDataSource methods:

void    setDataSource(String path)
Sets the data source (file-path or http/rtsp URL) to use.
void    setDataSource(Context context, Uri uri, Map<String, String> headers)
Sets the data source as a content Uri.
void    setDataSource(Context context, Uri uri)
Sets the data source as a content Uri.
void    setDataSource(FileDescriptor fd, long offset, long length)
Sets the data source (FileDescriptor) to use.
void    setDataSource(FileDescriptor fd)
Sets the data source (FileDescriptor) to use.

不幸的是它不接受任何形式的一个InputStream。有迹象表明，使用该打开的Andr​​oid应用程序的本地Web服务器老NPR代理code，例如下载内容的远程和输出请求的数据给任何监听套接字，但是那code为2年以上老它仍然作为标准完成这项任务（尽管很多人都报告说，口吃的问题，等等）。

Unfortunately it does not accept an InputStream of any kind. There are examples that use the old NPR proxy code that opens a local web server in the Android App, downloads content remotely, and outputs requested data to any listening sockets, however that code is more than 2 years old and it's still used as the standard for accomplishing this task (even though a lot of people report that there are stuttering issues, etc).

我看着在MediaPlayer类，并希望把它扩大到允许这种行为，但是很多实现通过本地code实现的，并从我读过，不同的设备制造商实现了原生音频功能不同（如果有的话，我不想去触摸它！:)）。

I've looked into the MediaPlayer class and wanted to extend it to allow this behaviour however a lot of the implementation is accomplished through native code, and from what I've read, different device manufacturers implement the native audio functionality differently (and if so, I don't want to touch it! :) ).

因此​​，什么是存储，并同时从远程服务器流进来的音频数据（MP3或OGG）的最佳方法，不丢弃该数据？ preferably与Android 2.2版本及以上，但输入任何可用的API将AP preciated。

So, what is the best method to store AND concurrently stream incoming audio data (MP3 or OGG) from a remote server, without discarding the data? Preferably with versions of Android 2.2 and above, but input on any available API would be appreciated.

推荐答案

建立一个本地代理是您最好的选择。我没有看过在NPR的例子，但我一直在使用娜迦做过类似。见我的答案<一个href=\"http://stackoverflow.com/questions/12701249/getting-access-to-media-player-cache\">here.

Building a local proxy is your best bet. I haven't looked at the NPR example, but I've done similar using Naga. See my answer here.
